Australian manufacturers, warehouses and even councils are deploying industrial robots, collaborative robots and robotic process automation to lift productivity and ease labour shortages. Every one of these systems is, at its core, a networked computer, but unlike a laptop it can move heavy machinery, weld, dose chemicals or steer a forklift. That combination of connectivity and physical reach makes secure integration a safety issue as much as a cyber one. Done well, automation is transformative; done carelessly, it carves a new path straight into your operations.
What makes robots and automation different
A robot is not a single device but a stack: a controller running an operating system, motion software with proprietary recipes, network interfaces, a teach pendant or HMI, and increasingly cloud connectivity for fleet management and analytics. RPA software bots are different in form but share the risk profile, because they typically run with stored privileged credentials and can touch finance, HR and customer systems at machine speed.
The threats that matter most in practice are:
- Manipulation of motion or logic that damages product, equipment or, worst of all, injures a worker.
- Disabling of safety functions such as speed and force limits on a cobot.
- Theft of intellectual property embedded in robot programs and production recipes.
- Use of the robot controller as a pivot to move deeper into the plant network.
- Credential abuse by RPA bots, where an over-privileged software robot becomes a powerful tool for an attacker.
Safety and security are one conversation
In a robotic cell, the cyber and the physical cannot be separated. A collaborative robot that works alongside people relies on software-enforced limits to keep its movements safe. If an attacker can alter that software or its parameters, they can turn a safe machine into a hazard. For this reason, every robot integration needs a safety risk assessment and a cybersecurity assessment that inform each other. The functional safety controls and the security controls protect the same outcome: nobody gets hurt and the process behaves as intended.
Segment robots into their own OT zone
The cardinal rule is the same as for any operational technology: keep robots off the flat corporate network. Place controllers in a dedicated, segmented OT zone, separated from enterprise IT by firewalls and an industrial demilitarised zone. This contains a compromise so that office ransomware cannot reach the production floor and a breached robot cannot reach the finance system. These ideas align with the Purdue model and the zones-and-conduits approach we explain in our guides to OT and ICS security fundamentals and IEC 62443.
Within that zone, apply defence in depth:
- Inventory every robot, controller and pendant with firmware versions, so you know your fleet and can act on vendor advisories.
- Harden controllers by disabling unused services and ports, changing default credentials, and removing internet exposure entirely.
- Validate firmware and program integrity so unauthorised changes to motion logic are detected before they run.
- Lock down the teach pendant and engineering access with role-based permissions, so only authorised, identified people can modify a robot’s behaviour.
- Broker remote vendor access through multi-factor, time-limited sessions in the DMZ rather than leaving a permanent tunnel open.
Build security in at the design stage
The cheapest and most effective time to address robot security is before anything is bought or installed. Retrofitting controls onto a commissioned, running cell is disruptive and often compromised by operational constraints, whereas decisions made during design cost almost nothing to get right. When you scope a new automation project, fold security into the requirements alongside throughput, cycle time and safety. Decide which OT zone the robots will live in, how remote support will be delivered, what logging the controllers must produce, and who will be permitted to change motion programs. Make these explicit acceptance criteria so the integrator delivers a secure system rather than handing you one to fix later.
This design-stage discipline matters even more as robots gain autonomy. Modern fleets increasingly rely on cloud dashboards, over-the-air updates and machine-vision systems, each of which adds connectivity and therefore attack surface. Autonomous mobile robots in a warehouse navigate by sensors that, if spoofed or degraded, could cause collisions or send stock to the wrong place. Treat every new sensing, connectivity or update feature as a control to be secured, not a convenience to be trusted.
The supply chain and the integrator
Most robot deployments involve at least three parties: the product supplier who builds the robot, the system integrator who installs and programs it, and you, the asset owner, who runs it. Security failures often fall through the gaps between them. The integrator may leave a default password in place or open a remote support port and consider it the vendor’s problem; the vendor may ship insecure defaults and assume the integrator will harden them.
Close those gaps contractually. Specify security requirements in the purchase and integration contract, require secure-by-default configuration, and include security acceptance testing before sign-off. Ask suppliers for a software bill of materials and a clear vulnerability disclosure and patching commitment. This is straightforward cyber due diligence applied to your automation programme, and it pays for itself the first time a vulnerability advisory lands and you already know exactly which assets are affected.
Securing RPA and software automation
Robotic process automation deserves its own discipline. Because RPA bots act on business systems with stored credentials, treat each bot as a privileged service account. Give it least privilege, rotate its secrets, store them in a managed vault rather than in scripts, and log every action it takes. An unmonitored RPA estate can quietly accumulate dozens of over-privileged bots that no one fully understands, which is a governance and audit problem as much as a security one. Where AI models are added to drive automation decisions, the same rigour applies, a topic our AI consulting practice addresses in depth.
Monitoring and incident response for automation
Once robots and bots are in production, you need to know when something is wrong. Robotic and automation traffic is highly predictable, which makes anomaly detection genuinely effective: an unexpected command to a controller, a new device appearing on the cell network, or an RPA bot running outside its scheduled window are all clear signals worth alerting on. Log controller access, program changes and pendant connections, and feed them to your monitoring so an investigation does not start from a blank page. Just as importantly, write and rehearse an incident response plan that covers automation. Operators and engineers should know how to safely stop or isolate a misbehaving robot, fall back to manual procedures where possible, and preserve evidence. A plan that has never been practised will fail under pressure, when a cell may need to be brought to a safe state in seconds.
Governance for an automated operation
As automation spreads across a site, ad hoc decisions accumulate into systemic risk. A governance framework, ideally aligned to ISO 27001 for the management system and IEC 62443 for the control environment, gives you consistent standards for how robots and bots are procured, deployed, monitored and retired. It also ensures security is considered at the design stage of each new project rather than bolted on after go-live, which is always cheaper and more effective.
Bringing it together
Integrating robots and automation securely is not about slowing down innovation. It is about making sure the productivity you gain is not quietly offset by new safety and cyber exposure. Inventory your fleet, segment it, harden the controllers, pin down integrator responsibilities, and govern your RPA estate. For organisations in manufacturing, logistics and the broader private sector, these steps turn automation into a durable advantage.

Frequently asked questions
Are industrial robots a cybersecurity risk?
Yes. A modern robot is a networked controller that drives motors with physical force. If compromised, an attacker could alter its programmed motion, disable safety functions, steal production recipes, or use it as a pivot deeper into the plant network. They must be treated as critical OT assets, not appliances.
What is the difference between RPA and physical robots?
Robotic process automation (RPA) is software that mimics human actions in business applications, such as copying data between systems. Physical or industrial robots are machines that move in the real world. Both carry security risk: RPA bots often hold privileged credentials, while physical robots can cause injury or process damage if manipulated.
How do I secure a collaborative robot working next to people?
Cobots rely on software-enforced safety limits on speed and force. Protect the controller and its network from tampering, validate firmware integrity, restrict who can change motion programs, and never expose the controller to the internet. A safety risk assessment must accompany the cybersecurity assessment, because the two are inseparable.
Should robots be on the same network as office IT?
No. Robots and their controllers belong in a segmented OT zone, separated from corporate IT by firewalls and a demilitarised zone. This contains any compromise and stops office ransomware reaching machinery. Remote vendor access should be brokered, multi-factor and time-limited rather than always-on.
Who is responsible for robot cybersecurity, the vendor or us?
Both, with clear boundaries. Under standards like IEC 62443 the product supplier secures the robot's design, the system integrator deploys it securely, and the asset owner operates and maintains it. Define these responsibilities in contracts and acceptance testing rather than assuming the vendor has covered everything.
